If an overheated or corroded resistor has left your cabin fan stuck on one speed or not working at all, the Dorman blower motor resistor, part number 973-547, is designed to replace it on the 2001-2003 Acura CL and 1999-2003 Acura TL. This Dorman blower motor resistor kit includes both a resistor and a harness pigtail, and it installs as a direct replacement for the original equipment on the listed applications.
- Resistor and harness together: Each kit includes a resistor and a harness pigtail, which Dorman calls essential for most repairs.
- Direct replacement: Replaces the original equipment resistor on the 2001-2003 Acura CL and 1999-2003 Acura TL.
- Designed to perform like the original: Made to work like the original equipment resistor, so it can bring back normal blower speed control when the old resistor is the fault.
- Engineering support: Backed by Dorman's team of engineers and quality specialists in the USA.
The blower motor resistor sets the fan's lower speeds by limiting the current that reaches the blower motor. Signs it may need replacing include a fan that runs only on its highest setting, speeds that no longer work, or no airflow from the vents. A switch, motor or wiring fault can cause the same symptoms, so diagnose the cause before you replace the resistor. For engine details and the full application list, see the "Vehicles it fits" section.

Frequently Asked Questions
Which Acura models does part 973-547 fit?
It is a direct replacement for the 2001-2003 Acura CL and the 1999-2003 Acura TL. See the "Vehicles it fits" section for engine details.
What's included with the Dorman HVAC blower motor resistor kit?
Each kit comes with a resistor and a harness pigtail. Dorman notes that the pigtail is essential for most repairs.
What does a blower motor resistor do?
It controls the blower motor's lower speed settings by limiting the current that reaches the motor. This lets you choose how hard the fan pushes air through the vents.
What are signs the blower motor resistor may need replacing?
A fan that runs only on high, speeds that no longer work, or no fan at all can come from a failed resistor. A switch, motor or wiring fault can cause these too, so diagnose the cause before replacing it.
How is the harness pigtail installed?
The pigtail connects the new resistor to the vehicle's wiring. Follow the vehicle service information for the correct connection method and the resistor's location.
